Description

Technical Field

[0001] This utility model belongs to the field of grain processing, specifically, it relates to a high-efficiency low-temperature baking equipment for grain raw materials. Background Technology

[0002] As an important part of human staple food, the advancement of grain processing technology directly affects the nutrition, taste and quality of food. In the field of grain processing, baking is a key process to achieve grain maturation, improve flavor and extend shelf life. It is widely used in whole grain foods such as oat flakes, brown rice flakes, and quinoa products, as well as in the pre-processing of miscellaneous grains. However, existing baking equipment has certain drawbacks when in use, such as uneven baking of miscellaneous grain powder and poor baking quality.

[0003] Chinese patent CN217429095U discloses a constant temperature roasting device for mixed grain powder. This device roasts and dries the mixed grain powder placed in the box by pouring different types of mixed grain powder into the corresponding placement box and then blowing hot air into the roasting chamber through a hot air blower. This structure can roast different types of mixed grain powder and facilitate their classification. However, when roasting the grain in the placement box, the grain pile structure in the placement box is fixed, and the grain at the bottom has a lower drying efficiency, resulting in uneven drying of the grain.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0016] The second bevel gear is sleeved and fixedly installed on the end of the second rotating shaft opposite to the first fixed plate, and the second bevel gear meshes with the first bevel gear.

[0017] Optionally, the vibratory feeder includes a feeder body and multiple sliding plates. The multiple sliding plates are fixedly installed on the feeder body and slidably disposed on a support plate. The support plate is provided with grooves for the multiple sliding plates to slide.

[0022] 2. Equipped with a drive mechanism and a vibrating plate, the vibrating plate can be slightly shaken by the drive mechanism to make the gap between grain particles more uniform and avoid uneven heating caused by grain clumping.

[0023] 3. By incorporating springs and movable plates, the design of the springs and movable plates can prevent the push plate from deforming or breaking due to hard impact, while also preventing the grain from being broken due to the hard squeezing of the push plate, reducing raw material loss, and enhancing the versatility of the device.

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Please see Figure 1-7As shown, this embodiment provides a high-efficiency low-temperature drying equipment for grain raw materials, including a housing 1, which defines a drying chamber 26. The opening of the drying chamber 26 is provided with a door 2. A drying fan 6 with its air outlet connected to the drying chamber 26 is fixedly installed on the housing 1. A support plate 18 is fixedly installed inside the drying chamber 26, and a placement tray 12 is placed on the support plate 18. A fixing frame 3 is fixedly installed on the housing 1. An electric telescopic rod 4 is fixedly installed on the fixing frame 3. The telescopic end of the electric telescopic rod 4 extends to the outside of the housing 1 and is rotatably provided with a first rotating shaft 10. The first rotating shaft 10 is coaxially arranged with the placement tray 12. A connecting plate 23 is fixedly installed on the end of the first rotating shaft 10 away from the electric telescopic rod 4. At least two mounting plates 8 are provided on the connecting plate 23. Multiple push plates 22 are provided on the mounting plates 8. The multiple push plates 22 between adjacent mounting plates 8 are relatively staggered. A rotating assembly 5 for driving the first rotating shaft 10 to rotate is provided on the housing 1.

[0038] Specifically, the housing 1 serves as the main body of the equipment, and the drying chamber 26 defined inside is the core space for grain roasting. The door 2 is used to seal the drying chamber 26 to maintain a stable temperature and humidity. The air outlet of the drying fan 6 is connected to the drying chamber 26. After starting, it can deliver hot air (or low-temperature heat source air) into the drying chamber 26 to provide the temperature environment required for grain roasting. The support plate 18 is fixed inside the drying chamber 26 to support the placement tray 12, which directly carries the grain raw materials to be roasted. The fixing frame 3 is fixed on the housing 1 to provide installation support for the electric telescopic rod 4. The telescopic end of the electric telescopic rod 4 extends to the outside of the housing 1 and is rotatably connected to the first rotating shaft 10. The first rotating shaft 10 is coaxial with the placement tray 12. When the electric telescopic rod 4 extends, it can drive the first rotating shaft 10, the connecting plate 23, and the mounting plate 8 towards the placement tray. The 12-direction movement brings the push plate 22 on the mounting plate 8 closer to the grains in the placement tray 12. When the rotating component 5 drives the first rotating shaft 10 to rotate, it will drive the connecting plate 23, the mounting plate 8 and the push plate 22 to rotate synchronously. Since the push plates 22 of the adjacent mounting plates 8 are relatively staggered, the rotating push plate 22 can turn the grains in the placement tray 12 in a "multi-directional and no dead angle" manner. After baking is completed, the electric telescopic rod 4 shortens and can drive the push plate 22 to detach from the placement tray 12, making it easier to open the box door 2 to take out the raw materials. The staggered push plate 22, in conjunction with the rotation of the first rotating shaft 10, can continuously turn the grains in the placement tray 12, avoiding the phenomenon of "overheating at the bottom and undercooking at the top" caused by long-term accumulation of grains, ensuring that each grain is evenly contacted with the heat source, improving the stability of the finished product quality, and thus solving the problem of uneven heating in traditional baking.

[0039] It should be noted that, in this embodiment, a cooling fan with an air outlet connected to the drying chamber 26 is fixedly installed on the housing 1. Of course, the drying fan 6, the cooling fan and the housing 1 are connected by a pipe, and a valve is connected to the pipe to control its opening and closing. In addition, the housing 1 is provided with an air pressure balance hole that connects the drying chamber 26 to the outside to ensure air pressure balance in the drying chamber 26. Furthermore, the housing 1 is provided with multiple temperature sensors with probes extending into the drying chamber 26. These temperature sensors are connected to an external controller to monitor the temperature inside the drying chamber 26. This is prior art and will not be described here.

[0040] In this embodiment, as Figures 1 to 5 As shown, the rotating assembly 5 includes a third rotating shaft 54, which is rotatably mounted on the housing 1. A first gear 52 is sleeved and fixedly installed on the third rotating shaft 54. A motor 51 for driving the third rotating shaft 54 ​​to rotate is fixedly installed on the fixing frame 3. A second gear 53 is sleeved and fixedly installed on the first rotating shaft 10. The first gear 52 meshes with the second gear 53. The length of the first gear 52 is greater than the length of the second gear 53.

[0041] In this embodiment, as Figures 3 to 5 As shown, the telescopic end of the electric telescopic rod 4 is fixedly mounted with a mounting bracket 11, and the first rotating shaft 10 is rotatably mounted on the mounting bracket 11.

[0042] In this embodiment, as Figures 1 to 5 As shown, a vibratory plate 9 is slidably mounted on the support plate 18, and the vibratory plate 9 is positioned opposite the placement plate 12. Multiple sets of tension springs 17, the other end of which is fixedly connected to the inner wall of the housing 1, are fixedly installed at the bottom of the vibratory plate 9. A first fixing plate 16 is fixedly installed inside the drying chamber 26. A second rotating shaft 14 is rotatably mounted on the first fixing plate 16 and the housing 1. A cam 15, which intermittently contacts the vibratory plate 9, is sleeved and fixedly mounted on the second rotating shaft 14. The cam 15 is located at the bottom of the vibratory plate 9. A drive mechanism 7 for driving the second rotating shaft 14 is provided on the housing 1. The drive mechanism 7 includes multiple second fixing plates 75, which are fixedly mounted on the housing 1. A rotating rod 71 is rotatably mounted on the plate 75. The rotating rod 71 is connected to the third rotating shaft 54 ​​via a belt drive mechanism 74. A first bevel gear 72 and a second bevel gear 73 are sleeved and fixedly mounted on the end of the rotating rod 71 away from the belt drive mechanism 74. The second bevel gear 73 is sleeved and fixedly mounted on the end of the second rotating shaft 14 away from the first fixed plate 16. The second bevel gear 73 meshes with the first bevel gear 72. Specifically, the vibration of the vibrating plate 9 controlled by the drive mechanism 7 can cause the placement plate 12 to shake slightly, making the gap between the grain particles more uniform and avoiding uneven heating caused by grain clumping. It is especially suitable for grain raw materials such as oats and quinoa that are prone to clumping.

[0043] In this embodiment, as Figures 3 to 5As shown, the vibratory feeder 9 includes a feeder body 91 and multiple sliding plates 92. The multiple sliding plates 92 are fixedly installed on the feeder body 91 and are slidably disposed on the support plate 18. The support plate 18 is provided with a sliding groove 20 for the multiple sliding plates 92 to slide.

[0044] In this embodiment, as Figures 3 to 7 As shown, a movable plate 24 is movably installed inside the mounting plate 8, and a movable groove 25 is provided inside the mounting plate 8 for the movable plate 24 to move. Multiple push plates 22 are fixedly installed at the first end of the movable plate 24, and multiple push plates 22 are movably installed on the mounting plate 8. Multiple sets of springs 13 are provided inside the movable groove 25 that abut against the second end of the movable plate 24. Specifically, the design of the springs 13 and the movable plate 24 can prevent the push plates 22 from deforming or breaking due to hard collisions (such as clumps of grain or vibration of the placement tray 12), and at the same time prevent the grain from being broken due to the hard squeezing of the push plates 22, thereby reducing raw material loss and improving the versatility of the device.

[0045] In this embodiment, as Figures 3 to 5 As shown, a limiting plate 19 is fixedly installed on the inner wall of the drying chamber 26 relative to the support plate 18, and an anti-collision pad 21 is fixedly installed at the bottom of the limiting plate 19.

[0046] Working principle:

[0047] The grains to be roasted are evenly placed into the placement tray 12, and then the placement tray 12 is placed on the support plate 18, so that the placement tray 12 is positioned between the support plate and the limiting plate 19. Then the door 2 is closed, and the roasting temperature (60-120℃), time, and fan speed are set by the external controller. The drying fan 6 starts working and delivers hot air to the drying chamber 26. The mounting plate 8 is moved by the electric telescopic rod 4, so that the push plate 22 is inserted into the grains in the placement tray 12 and the bottom of the push plate 22 is in contact with the bottom wall of the placement tray 12. Then the motor 51 controlled by the external controller drives the third rotating shaft 54 ​​to rotate, and the first gear 52 drives the second gear 53 to rotate, so that the first rotating shaft 10 drives the connecting plate 23 and the mounting plate 8 to rotate. The push plate 22 begins to turn the grains. At the same time, the third rotating shaft 54 ​​is driven by the belt drive. The mechanism 74 drives the rotating rod 71 to rotate, and at the same time, the meshing of the first bevel gear 72 and the second bevel gear 73 drives the second rotating shaft 14 to rotate. The second rotating shaft 14 drives the cam 15 to intermittently push the vibrating plate 9, which, together with the tension spring 17, forms up-and-down vibration. The vibration is transmitted through the placement tray 12, making the grain distribution more even. When the vibrating plate 9 drives the placement tray 12 to vibrate, the push plate 22 drives the movable plate 24 to compress the spring 13 to achieve buffering. After baking, the electric telescopic rod 4 retracts to disengage the push plate 22 from the placement tray 12, which can activate the cooling mode or allow natural cooling. The door 2 is opened, the placement tray 12 is taken out, and one batch of processing is completed. The overall structure and operation steps are simple, which can ensure that the grains in the placement tray 12 are heated evenly, ensuring that each grain is heated evenly and avoiding local overheating and scorching, thus solving the problem of uneven heating in traditional baking.
